I can't get my Mac mini to accept discs. I'm almost positive there is not one already in it. I tried to search for a solution and none of them worked. (Shutting down and holding the mouse button, etc.) I read that the SuperDrive can fail because of a fan issue. Is that true? Thinking about it, I haven't heard my fan in a while (it was always loud enough that I could hear it especially on startup. I took the bottom off and it's spinning, but slow. The computer is working fine otherwise. Any help would be greatly appreciated.
